Product Applications
Nano-alumina powder is produced via aerosol salt ablation method.PreparationHigh purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual impurities, low bulk density, easy to disperse, stable crystal phase, high hardness, and excellent dimensional stability. It can be widely used for reinforcement and toughening of various plastics, rubber, and ceramic products, particularly in improving the density, smoothness, thermal shock resistance, fracture toughness, creep resistance of ceramics, as well as the wear resistance of polymer material products. Additionally, due to its excellent far-infrared emission properties, nano-alumina is used as a far-infrared emitting and thermal insulation material in chemical fiber products and high-pressure sodium lamps. Furthermore,Alpha-phase alumina has high resistivity and good insulating properties, making it suitable for applications such asYGAIn the main components of laser crystals and integrated circuit substrates.
1. The main component of both rubies and sapphires is aluminum oxide. Products made from high-purity nano-aluminum oxide powder have fewer impurities, brighter colors, and greater uniformity.
2. Aluminum reacts with O2 in the air, forming a dense layer of aluminum oxide film that covers the surface of aluminum exposed to the air.
3. Aluminum is a good conductor of electricity and heat. The crystalline form of aluminum oxide, due to its high hardness, is suitable for use as an abrasive material and cutting tool.
4. Nano-alumina powder is commonly used as a medium for chromatographic analysis.
5. Application of nano-alumina powder in lighting: raw materials for long-afterglow phosphors and rare-earth tricolor phosphors, high-pressure sodium lamp translucent tubes, LED lights, etc.
Packaging and Storage
This product is filled with inert gas.Plastic bagPackaging: Store sealed in a dry, cool environment. Avoid exposure to air to prevent moisture-induced oxidative agglomeration, which may affect dispersion performance and usability. Packaging quantities can be customized according to customer requirements, with sub-packaging available.
